Brilliant, 7 years later and still the clearest explanation how to wire up a balance lead.

Great explanation on how these leads get wired. I'm old school NiCd RC fellow. I'm new to the Lipo scene. I was recently manually balance charging LiO 18650 cells in some Milwaukee packs which have sat for years unused, but new. I have a 4 cell (individual charging slots for 1 cell each) charger from the vape/flashlight market. I made some cell adapters to place into the charger with some test leads (j-hooks) to attach to tabs on assembled packs. The goal being to charge each cell individually with each port of the 4 port charger. I used this successfully to bring cells up to 4.2V each. However, I was only able to use one charge bay, and do it one cell at a time. I bought a different 8 cell charger (for loose cells), but it would fault out when more than one cell was connected. I made a bunch of blank cells with wire leads to place in charger bays. I'd like to try to use them all at once, as I have large 12ah tool packs I'd like to bring into balance. Would using diodes maybe help? I'd like to avoid removing tabs. Should I just break down and buy a hobby balance charger? lol I actually have a lot of 4s, 5s, 7s leads from other projects.
